Moving a jug (5)

Ross

I believe the answer is:

astir

'moving' is the definition.
(I've seen this in another clue)

'a jug' is the wordplay.
'jug' becomes 'stir' (both are slang for prison).
'a'+'stir'='ASTIR'

(Other definitions for astir that I've seen before include "In motion - out of bed" , "Starting to move" , "Moving; out of bed" , "This isn't still" , "Excitedly moving" .)

I've seen this clue in the Evening Standard and The Globe and Mail.
